Terms of Use

Who you are contracting with

Mesura is published by Vladislavs Petkuns, an individual developer, contactable at mesura.app@gmail.com. Throughout these terms "you" means the person using the app; if you use it for an employer, you confirm you are authorised to accept these terms on that organisation's behalf.

These terms apply together with our Privacy Policy, which forms part of this agreement.

Your licence to use Mesura

We grant you a personal, worldwide, non-exclusive, non-transferable, revocable licence to install and use Mesura on devices you own or control, for your own work — including commercial construction work. That is what the app is for.

We keep ownership of the app itself: the software, the calculation engines, the interface design, and the Mesura name and branding. Nothing in these terms transfers any of that to you.

Estimates, not engineering advice

Mesura calculates quantities from the numbers you give it, using standard construction formulas and the waste allowances you configure. The results are estimates for planning and ordering. They are not a design, not a specification, and not professional engineering, surveying, architectural or building-control advice.

Checking every result before relying on it is your responsibility. In particular:

• Your inputs decide the output. A mistyped dimension, the wrong unit, or a coverage rate that does not match the product you actually bought will produce a confidently wrong answer.
• Local rules override the app. Building codes, standards and accepted practice differ by country, region and project. Mesura does not know which apply to you and makes no attempt to enforce them.
• Manufacturer data wins. Coverage rates, bag yields, mortar ratios and spread rates vary by product. Always use the figures printed on what you are buying.
• Site conditions are not modelled. Substrate, moisture, temperature, tolerances, cuts, openings, structural loads and real waste on the job can all move the true number.

For anything structural, load-bearing, safety-critical or subject to inspection, have a qualified professional check the figures. Do not use Mesura as the sole basis for a structural decision.

The spirit level

The level uses your device's accelerometer. Its accuracy depends on your hardware, on how that sensor was calibrated at the factory, on how flat the phone sits against the surface, and on the case you have on it.

It is a convenience tool for rough checks. It is not a certified or calibrated measuring instrument and must not be used where an accredited measurement, a legal tolerance or a safety margin is required. Use a real level — and a calibrated one where the job demands it.

Mesura Pro — a one-time purchase

Mesura is free to use. Mesura Pro unlocks the paid features for a single one-time payment.

• It is not a subscription. There is nothing to auto-renew and nothing to cancel, and you will not be charged again.
• It is permanent for the store account that bought it, and can be restored on your other devices signed in to that account with Restore purchases in Settings.
• Family Sharing follows the store's rules and the setting on the product; where it is enabled, your family group can use the unlock.
• The price varies by country and may change over time. The price shown in the app before you confirm is the price you pay, in your local currency, including any tax the store adds.

Payment is taken and processed by Apple or Google. We never receive your payment details.

Refunds

Because the purchase is made through the store, refunds are handled by Apple or Google, not by us. Request one through Apple's Report a Problem page or through Google Play. We have no ability to grant, block or reverse a store refund. If a refund is granted, the Pro features stop working.

This does not affect the statutory rights described further below.

Your content

Your projects, measurements, notes, lists and exports are yours. We claim no ownership of them and, as the Privacy Policy explains, we never receive them.

Because that data lives on your device, backing it up is your responsibility. Uninstalling the app, resetting or losing the device, or clearing the app's data will delete your projects, and we cannot recover them for you. Export anything you cannot afford to lose.

What you may not do

You agree not to:

• copy, sell, rent, sublicense or redistribute the app or any part of it;
• reverse engineer, decompile or disassemble it, except to the extent applicable law expressly permits despite this restriction;
• remove or obscure any copyright, trademark or other proprietary notice;
• use the app in breach of any law, or in any way that damages, disables or interferes with it or with the services it relies on;
• circumvent or attempt to circumvent the Mesura Pro purchase, or use a modified or unauthorised copy of the app;
• use automated means to extract the app's calculation logic or data at scale.

Availability, updates and changes

Mesura works offline for its core functions, but purchases, restore and the update check need a connection. We do not promise that the app or those services will be available without interruption or free of defects.

We may update the app and may add, change or remove features. We may end support for older operating systems or older app versions; once a version is unsupported the app may ask you to update before continuing.

If we ever have to withdraw a paid feature entirely, we will give reasonable notice in the app.

Third-party services

Mesura uses Google Firebase for analytics, crash reporting and configuration, and RevenueCat for purchase validation. Links in the app may take you to the App Store, Google Play or a web page we do not control. Those services have their own terms and privacy policies, and we are not responsible for them.

No warranty

To the fullest extent the law allows, Mesura is provided "as is" and "as available", without warranty of any kind, whether express, implied or statutory. We specifically disclaim the implied warranties of merchantability, fitness for a particular purpose, accuracy and non-infringement.

We do not warrant that the app will meet your requirements, that its calculations will be correct for your project, that it will run without interruption or error, or that defects will be corrected.

Some jurisdictions do not allow the exclusion of implied warranties, so parts of this section may not apply to you. Nothing here removes consumer rights that cannot be waived.

Limit of our liability

To the fullest extent the law allows, we are not liable for indirect, incidental, special, consequential or punitive damages, nor for lost profits, lost revenue, lost time, lost or corrupted data, wasted material, rework, delay, or the cost of substitute goods or services — even if we were told such damage was possible.

Our total liability for all claims connected with Mesura is limited to the greater of the amount you paid for Mesura Pro in the twelve months before the claim, or EUR 50.

Nothing in these terms limits liability that cannot lawfully be limited — including liability for death or personal injury caused by negligence, for fraud or fraudulent misrepresentation, and, where you are a consumer, for intent and gross negligence.

This allocation of risk is reflected in what the app costs. If you are not willing to accept it, your remedy is to stop using Mesura.

Your responsibility to us

If you use Mesura in breach of these terms or of the law and that leads a third party to bring a claim against us, you agree to cover our reasonable costs, damages and legal fees arising from it. This does not apply where the claim is caused by our own breach or negligence, and it does not apply to consumers where local law prohibits it.

Ending this agreement

You can end it at any time by deleting the app. We can end it if you materially breach these terms, in which case your licence stops and you must stop using and delete the app.

Ending the agreement does not entitle you to a refund except where the law or the store's policy gives you one. Provisions that by their nature should survive — ownership, disclaimers, liability limits, indemnity and governing law — survive termination.

Additional terms for the Apple App Store

The following applies when you obtained Mesura from the Apple App Store, and is required by Apple:

• These terms are between you and us only, not with Apple. Apple is not responsible for the app or its content.
• The licence granted above is limited to using Mesura on any Apple-branded device you own or control, as permitted by the Usage Rules in the Apple Media Services Terms and Conditions.
• Apple has no obligation to provide maintenance or support for the app.
• If the app fails to conform to any applicable warranty, you may notify Apple, and Apple will refund the purchase price. To the maximum extent permitted by law, Apple has no other warranty obligation of any kind, and any other claims, losses, liabilities, damages, costs or expenses attributable to a failure to conform to a warranty are our responsibility.
• Apple is not responsible for addressing any claim by you or a third party relating to the app or your possession or use of it, including product liability claims, any claim that the app fails to conform to a legal or regulatory requirement, and claims arising under consumer protection or similar legislation.
• If a third party claims that the app or your use of it infringes their intellectual property, we, not Apple, are solely responsible for the investigation, defence, settlement and discharge of that claim.
• You represent that you are not located in a country subject to a US Government embargo or designated as a "terrorist supporting" country, and that you are not listed on any US Government list of prohibited or restricted parties.
• Apple and its subsidiaries are third-party beneficiaries of these terms and, on your acceptance, have the right to enforce them against you.
• Questions, complaints or claims about the app should be directed to us at mesura.app@gmail.com.

Additional terms for Google Play

Where you obtained Mesura from Google Play, your use is also subject to the Google Play Terms of Service. This agreement is between you and us, not with Google, and Google is not responsible for the app. Where these terms conflict with the Google Play Terms of Service in a way that affects your rights, the Google Play terms prevail to the extent of the conflict.

If you are a consumer in the EU, EEA or UK

Nothing in these terms affects your mandatory statutory rights, including your rights where digital content is faulty or not as described.

Digital content bought through an app store is delivered immediately, and by purchasing you agree to that immediate performance; under EU rules the 14-day right of withdrawal falls away once delivery has begun with your consent. In practice Apple and Google both operate refund policies that are often more generous — use them.

If you have a complaint, write to us first: we would much rather fix it. You may also contact the consumer protection authority in your country. We are not obliged, and do not undertake, to take part in dispute resolution proceedings before a consumer arbitration board.

Governing law and jurisdiction

These terms are governed by the law of Latvia, excluding its conflict-of-law rules and the UN Convention on Contracts for the International Sale of Goods.

If you are a consumer, this choice of law does not deprive you of the protection of the mandatory consumer law of the country where you live, and you may bring proceedings in the courts of that country. If you are a business, the courts of Latvia have exclusive jurisdiction.

Changes to these terms

We may update these terms — when the app gains a feature, for instance, or when the law changes. The date at the top shows the current version. If a change materially reduces your rights we will tell you in the app before it takes effect, and continuing to use Mesura after that means you accept the new terms. If you do not accept them, stop using the app and delete it.

General

If any provision is found unenforceable it is limited or removed to the minimum extent necessary, and the rest stays in force. Our failure to enforce a provision is not a waiver of it. You may not transfer your rights under these terms without our consent; we may transfer ours to whoever takes over the app, on notice to you. These terms and the Privacy Policy are the entire agreement between us about Mesura.

These terms are published in several languages for convenience. If a translation conflicts with the English version, the English version prevails — except where mandatory local consumer law says otherwise.
